Abstract. Exploring the snow thickness at the Mount Everest has long been a topic of interest for studying geodesy, cryosphere and climate change, but has not yet been measured successfully. Here, we report the ground-penetrating radar survey of snow thickness along the northern slope of the Mount Everest in May 2022. Our radar measurements display a gradual increasing transition of snow thickness along the north slope, and the mean snow thickness estimates at the Mount Everest is approximately 9.5 m. This updated snow thickness at the Mount Everest is much deeper than previously reported values (0.9~3.5 m).

Short summary
There are very strong scientific and public interests to know the snow thickness at the Earth summit. However, previous attempts to measure snow thickness were not successful. Our measurements in May 2022 provide the first clear radar image of snowpack at the top of Mount Everest in the world.The snow thickness at the Earth summit was averaged to be approximately 9.5 m. This updated snow thickness is considerably deeper than previously reported values during the past five decades (0.9~3.5 m).
